Q1:

Materials in order of decreasing electrical conductivity are

A aluminium, silver, gold, copper

B gold, silver, copper, aluminium

C copper, silver, gold, aluminium

D silver, copper, gold, aluminium

ANS:D - silver, copper, gold, aluminium

I think the answer is correct. Silver has the lowest resistivity therefore it has the highest conductivity. Followed by copper, gold then aluminum.
